I've compiled a list of some of the Greek language works available in Community Pricing:
E. A. Sophocles Collection (4 vols.) $20
The ONLY collection with a Byzantine-era Greek dictionary. This enables the student to fast forward to what the meaning of the word became, rather than just looking back to what it once was. The NT meaning may be somewhere in-between.
http://www.logos.com/product/8513/e-a-sophocles-collection
"Sophocles devoted his life to the study of Ancient, Byzantine, and Modern Greek. The four volumes in this collection represent the culmination of decades of research and study on the Greek language. His grammars and lexicons have been all been recognized as major contributions to Greek scholarship. "
Georg Curtius Greek Studies Collection (4 vols.) $30
http://www.logos.com/product/8534/georg-curtius-greek-studies-collection
"This collection provides the reader with a basic introduction to Greek linguistics in A Grammar of the Greek Language as well as more in-depth studies with Principles of Greek Etymology and a detailed study of verbs in The Greek Verb: Its Structure and Development."
Von Soden Greek New Testament (4 vols.) $8
http://www.logos.com/product/15705/von-soden-greek-new-testament
"Von Soden introduced a new theory of classifying manuscripts, thus making his critical edition of the Greek text a essential tool for the student of the New Testament.
With Logos, you can incorporate von Soden’s critical text into your study of textual variants. When opened side-by-side with the Nestle-Aland and Tischendorf apparatuses, you have the amazing opportunity to see for yourself the history and transmission of the New Testament text."

http://www.logos.com/product/15750/a-copious-phraseological-english-greek-lexicon
"Frädersdorff’s A Copious Phraseological English-Greek Lexicon is intended to assist the student of Greek in composing Greek sentences by listing English words followed by their corresponding Greek definition."
Woodhouse, English-Greek Dictionary: A Vocabulary of the Attic Language $14
http://www.logos.com/product/15748/english-greek-dictionary-a-vocabulary-of-the-attic-language
"With Woodhouse’s dictionary, the user looks up an English word in order to find the equivalent Greek meaning, making Woodhouse’s work unique with respects to other traditional Greek lexicons. And because the sources Woodhouse used for his examples were taken from the Classical writers of Greek literature, if you have the Perseus Classics Collection in in your library you can quickly jump to a reference and read it in its own original context."
C. D. Yonge’s An English-Greek Lexicon $6
http://www.logos.com/product/15746/an-english-greek-dictionary

Cremer’s Biblico-Theological Lexicon of New Testament Greek $22
http://www.logos.com/product/15703/biblico-theological-lexicon-of-new-testament-greek
"Cremer’s lexicon is a valuable resource for tracing a Greek word's history from Classical Greek through the Septuagint, and finally into the New Testament."

http://www.logos.com/product/8512/a-critical-lexicon-and-concordance-to-the-english-and-greek-new-testament
